Power-to-gas VIEgMAN Storing excess power in the gas grid

Offshore wind energy Onshore wind energy Methanisation Excess power from renewables Methane (CH 4) Combined heat and power units Transfer station Heating network Natural gas grid Power grid Excess power is converted into methane using electrolysis and CO2. The methane can be transported and stored in the gas grid, and can be converted into power as required. Power-to-gas: Storing excess power in the gas grid Excess power Excess power Producing hydrogen from Methane is injected directly excess power into the natural gas grid.

The methanisation of excess power makes conventional power stations redundant The German natural gas grid has immense storage capacities. This means that the production of synthetic methane from excess wind or solar power with the help of power-to-gas technology now presents real opportunities. MicrobEnergy GmbH – specialists in methanisation MicrobEnergy GmbH, which is part of the Viessmann Group, develops and sells microbiological products and technical system components. The company, furthermore, also specialises in process control and optimising biological systems. Microorganisms convert...
